1 Claim.

This invention relates to window construction and particularly that part of the window forming a portion of the two slidably mounted window sashes where the same meet, and the primary object of the invention is to provide a positive seal between the meeting rails of two slidably mounted sashes which will cooperate with the joint betweenthe meeting rails to render the same air tight.

Another object of this invention is the contemplation of a drainage means forming a part of the window structure and embodied in the meeting rail of one of the slidably mounted sashes.

A yet further object of the invention is to provide a novelty constructed meeting rail for window sashes which incorporates means for sealing the joint in combination with a drainage system for the window structure which forms a part of the meeting rails.

Minor objects and details of construction embodying these inventions will appear during the course of the detailed specification referring to the accompanying drawing, wherein Figure l is a side elevation of a window structure made in' accordance with this invention.

Fig. 2 is an enlarged vertical cross section through the meeting rails taken on line 11-11 of Fig. 1, the meeting rails being slightly spaced apart.

Fig. 3 is a similar view showing the meeting rails in the closed position with the resilient pad slightly compressed.

Fig. 4 is a horizontal cross section through the upper sash showing the series of drain holes.

Fig. 5 is an inverted horizontal cross section through the upper sash showing the positioning of the resilient pad.

Like reference numerals refer to similar parts throughout the several views of the drawing wherein has been illustrated but the preferred form of the invention, and wherein the numeral 8 designates a window frame of ordinary construction which slidably supports an upper and a lower window sash 10 and 12 respectively. The

upper window sash 10 has a meeting rail 14 wherein is formed a longitudinal groove 16 for the reception of a portion of the hereinafter described meeting rail of the lower sash 12. An up-turned flange 18 spaces groove 16 inwardly from the edge of meeting rail 14 and terminates in a plane spaced below the upper edge of meeting rail 14. The inner side of flange 18 forming one wall of groove 16 may be inclined slightly if desired, and, to carry out one of the important features of the invention, a series of drain holes 20 should be provided which are formed through the meeting rail 14 along the bottom of groove 16. Drain holes 20 extend from the bottom of groove 16 to a point exteriorly of rail 14 so that moisture collecting on the window or water accumulating along groove 16 is drained therefrom.

To form an effective joint between meeting rail 14 of upper sash 10 and meeting rail 22 of lower sash 12, the rails are caused to interlock as clearly illustrated in Fig. 2.- A flange 24 formed by rail 22 is disposed in the same plane as groove 16 formed in meeting rail 14. Likewise, a groove 26 is formed along meeting rail 22 to cooperate with flange 18 when the window sashes are closed.

The inner side of flange 24 may be slightly inclined if desired, to correspond with the angle of inclination formed by the inner wall of flange 18. This construction forms an effective interlocking of the upper and lower window sashes 10 and 12 respectively under normal conditions, but in the event it is desired to provide a tighter joint the resilient pad 28 may be secured along the upper-most portion of groove 26. Thus when the meeting rails are moved together and the grooves and flanges thereof move into cooperative relation, the edge of groove 18 presses against pad 28 and effectively seals the joint between the two sashes l0 and 12.

This pad should extend along the entire length of groove 26 and may be of any suitable resilient material of a thickness sufficient to take up any play existing between the two rails 14 and 22, caused by the change in weather conditions.

It is understood that refinements of construction made in accordance with the spirit of this invention might be incorporated in window structures of many different kinds and makes, and,

while the preferred form of the invention has been set forth and described, it is desired to be limited only by the scope of the appended claim.

What is claimed as new and desired to be secured by Letters Patents is:

A window, comprising a frame having an upper and a lower sash each slidably mounted therein for rectilinear, reciprocating, vertical movement, a groove and tapered flange formed by the meeting rail of each sash respectively, the groove and flange of the upper sash engageable with the flange and groove respectively of the lower sash when the window is closed, a resilient pad positioned along the bottom of the groove formed in the meeting rail of the lower sash engageable by the edge of the flange of said upper sash when the window is closed, the free end of the flange on the lower sash being spaced apart from the bottom of the groove formed in the upper sash whereby a channel is formed therebetween, and a series of drain holes formed through the upper sash meeting rail to communi cate with said channel.
